Thau, who lists Buzzwire and Openwave among his former employers, joined Twitter in 2009 and is said to have been instrumental in its acquisition of We Are Hunted, the company that powers Twitter #music's recommendation engine.

Twitter lifted the lid on its #music app last week. The iOS and web-based service provides users with music recommendations based on their activity on the microblogging website.

A native app for Android devices is thought to be in development, while Windows Phone 8 and BlackBerry versions are yet to be announced.

Stone announced Jelly last month, but remained tight-lipped about the service it will provide.
